Abstract Details


To evaluate refractive and visual outcomes and complications associated with Implantable Collamer Lens (ICL) implantation to correct high myopia.


Fernández-Vega Ophthalmological Institute, Oviedo, Spain.


Retrospective observational case series study involved 61 eyes of 45 patients, of which 28 (62.2%) were women and 17 men (37.7%). The mean age of the patients at the time of surgery was 35.08 ± 7.08 years. Uncorrected (UCVA) and best-corrected distance visual acuity (BCVA), refraction, vault and adverse effects were evaluated after five years ICMV4 ICL model implantation.


Mean spherical equivalent (SE) dropped from -18.32±2.37 diopters (D) preoperatively to -0.88±0.52D 5-years postoperatively. The mean Snellen decimal BCVA and UCVA were 0.73±0.23 and 0.55±0.26, respectively. More than 50% of eyes achieved 20/25 or better BCVA postoperatively. The safety index was 1.26±0.32. Forty eyes (65.5%) had UCVA of 20/40 or better postoperatively. The efficacy index was 0.99±0.42. Mean central vault was 475.28±216.38µm postoperatively. No eyes showed central contact between ICL and crystalline lens. Nevertheless, 10 eyes showed peripheral contact; with a central vault between 150 and 260µm. Two eyes developed anterior subcapsular cataract, although just one eye required cataract surgery.


These outcomes showed that ICMV4 ICL is a safe, predictable and effective procedure to correct high levels of myopia over 5-years postoperatively. Furthermore, we suggested a minimum central vault greater than 260 µm to avoid the anterior subcapsular development in patients implanted with an ICL of -20.00 D.
